Matrix metalloproteinases (MMPs) are a family of zinc-dependent endopeptidases. MMPs have been characterized in detail in mammals and shown to play key roles in many physiological and pathological processes. Although MMPs in some plant species have been identified, the function of MMPs in biotic stress responses remains elusive. | Tomato Sl3-MMP a member of the Matrix metalloproteinase family is required for disease resistance against Botrytis cinerea and Pseudomonas syringae pv. tomato DC3000
